SECTIONAL DRAIN-TILE.

Application filed October 9, 1911.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Serial No. 653,623.

To all whom it may concern:

Be it known that I, J OHN M. VVILSoN, a citizen of the United States, residing at Lottie, in the parish of Pointe Coupee and State of Louisiana, have invented certain new and useful Improvements in Sectional Drain-Tiles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sectional drain tile, and has for its object to produce a roduct of this nature, which will be more efficient in use, and less liable to clog with silt or soil than has been the case with drain, tile heretofore used.

To these ends the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views :Figure 1 is a perspective view of a tile made in accordance with my invention; Fig. 2 is a sectional view of a slightly modified form of tile; and, ig. 3 is a diagrammatic sectional view of the soil showing my tile in use.

1 and 2 represent top sections of my tile made of any suitable material such as metal for example, or other material which may be found suitable for this purpose, and 3 and arepresent corresponding bottom sections of my tile made of material similar to that of the sections 1 and 2.

In the form of the invention shown in Fig. 1 the top sections 1 and 2 are preferably joined together along the flanges 5 and 6 as by the rivets 7 and the bottom sections 3 and 4 are likewise joined together through the flanges 8 and 9 as by the spacing rivets 10, leaving an upwardly extending passage 11. The sections 1 overlap the sections 3 as indicated, and the overlapping edges are joined together as by the rivets 12 leaving an open passage 13. In the same way the sections 2 overlap the sections 1 and are joined together as by the spacing rivets 14 leaving an upwardly extending passage 15 therebetween. The rivets 10 and 14 are so arranged, as by having thickened necks shown in Fig. 2, that the sections are secured together and yet spaced apart, permitting the passage of water therebetween. Any suitable form of spacing rivet, many 0 which are well known in the art. will be suitable for this purpose. 6 are preferably secured sufliciently close together as to enable little or no water to pass therethrough while the other passages 11, 13 and 15 are left sufliciently open to permit water to readily pass upwardly through the same, but not with suflicient velocity to carry sand, silt or sediment into the channel of the tile against the action of gravity.

In the modification shown in Fig. 2 the construction is substantially the same, except the flanges 5 and 6 arespaced sufficiently far apart to provide a passage 16, and the flange 5 is provided with an overhanging lip 17 providing the upwardly extending passage 18 between said lip and the flange 17.

It will be observed that in the construction shown in Fig. 1, when the tile is buried in the ground, as illustrated in Fig. 3, water will not be enabled to enter between the flanges 5 and 6, but must flow over the sides of the tile and up through the passages 13 and 15, or through the passage 11 in order to enter the tile. The passages being restricted as stated, the flow of water will not be sufficient to carry soil or silt against the action of gravity, and therefore little, if any, of such material will enter the tile with the water. Likewise in the construction shown in Fig. 2, water can only enter the tile by flowing upwardly through the passages 11, 13, 15 or 18, and therefore in this case also the soil or silt will be prevented by gravity from entering the tile.

It results from the constructions just disclosed that tile built in accordance with this disclosure will be less liable to fill up or beand therefore such tile will not require repairs as often as the old style.

It is obvious that those skilled in the art may vary the details of construction and the arrangement of parts without departing from the spirit of my invention, and there fore I do not wish to be limited to the above disclosure except as may be required by the claims.

What I claim is 1. In a sectional drain tile the combination of top and bottom overlapping sections; and means to so secure said sections together The flanges 5 and I come clogged than tile heretofore proposed,

as to leave an upwardly extending passage for water between said sections, substantially as described.

2. In a sectional drain tile, the combination of overlapping top and bottom sections, said bottom sections provided with flanges; means to so secure said overlapping sections as to leave an upwardly extending passage between them; and means to so secure said flanges as to have an upwardly extending passage entering said tile, substantially as described.

3. A drain tile provided with top sections provided with flanges, one of said flanges provided with an overhanging lip adapted to overlie the other flange; so securing said flanges being further and with means for together as to form an upwardly and down wardly extending passage into said tile substantially as described.

4. A drain tile provided with top sections having an upwardly and downwardly extending passage between them; with bottom sections having an upwardly extending passage between them; and with means for so securing said top and bottom sections as to provide upwardly extending passages enter- 7 ing said tile, substantially as described.

In testimony whereof, I aflix my signature, in presenceof two witnesses.
